Raypak
Setting
HC1
REGULATOR 1 (folder with “rE1” label)
Heat/Cool Mode. If set to H
the generic regulator actuates for hot operation. If set to C the generic
regulator actuates for cold operation

dF1
diFferential. Relay 1 tripping differential. The regulator stops on
reaching the Setpoint value (as indicated by the adjustment probe),
and restarts at temperature value equal to the Setpoint 1 plus (o
minus depending on HC1) the value of the differential.

dn1
REGULATOR 1 PROTECTIVE DEVICE (folder with “rE1” label)
Delay time in activating the regulator relay after switch-on of
instrument.

do1
Delay after switch off. The indicated time must elapse between
switch-off of the regulator relay and the successive switch-on.
0...250

di1
Delay between switch-ons. The indicated time must elapse
between two successive switch-ons of the regulator.
0...250
0
dE1
Delay before switch-off. The indicated time must elapse between
switch-off request and the switch-off of the regulator.
PLEASE NOTE: for par. dn1, do1, di1, dE1 0= not active

On1
On time (regulator 1).
Regulator activation time in the event of faulty probe. If set to “1”
with OF1 at “0” the regulator is always on, while at OF1 >0 it
functions always in duty cycle mode.
0...250
0
OF1
OFF time (regulator 1). Regulator in disabled state time in the
event of a faulty probe. If set to “1” with On1 at “0” the regulator
is always off, while at On1 >0 it functions always in duty cycle
mode.
